      This introduced a new erasure coding policy named XOR-2-1-64k using the simple XOR codec, and it can be used to evaluate HDFS erasure coding feature in a small cluster (only 2 + 1 datanodes needed). The policy isn't recommended to be used in a production cluster.

      Description

      So far, "hdfs erasurecode" command supports three policies, RS-DEFAULT-3-2-64k, RS-DEFAULT-6-3-64k and RS-LEGACY-6-3-64k. This task is going to add XOR-2-1-64k policy to this command.
